cretes according DIN EN 206-1/DIN 1045-2.
Mainly TAPP Portland Cement CEM I 52.5 N is used for concretes for which hig-
her and highest strength classes must be achieved and/or high early strengths are
needed.
Concrete precast industry
A preferred field of use of TAPP Portland Cement CEM I 52.5 N is the concrete
precast industry. This cement contributes significantly to the economical production
of precast components made from pretensioned concrete in direct bond.
Concrete additives:

The addition of concrete additives is permitted according DIN EN 206-1/DIN 1045-2, if
they conform to the relevant regulations or a general technical approval is available.
Concrete additives with approval may only be used under the conditions as stated
in the approval document. For the production of pre-tensioned concrete with direct
bond according DIN 1045-1 as concrete additives only fly-ash and silica fume or inert
powdered minerals according DIN EN 12620 and pigments with proven harmlessness
for pre-tensioning steel, may be used.
An initial test according DIN EN 206-1/DIN 1045-2 is necessary for the addition of
concrete additives.
Concrete admixtures:

The addition of concrete admixtures is permitted according DIN EN 206-1/DIN 1045-
2, if they conform to the relevant regulations or a general technical approval is available

and when used under the conditions as stated in the approval document.
An initial test according DIN EN 206-1/DIN 1045-2 is necessary for the addition of
concrete admixtures.
